Configuring Ports As Edge Ports - H3C S5810 Series Operation Manual

If the maximum rate setting of a port is too big, the port will send a large number of MSTP packets within
each hello time, thus using excessive network resources. We recommend that you use the default
setting.
Configuration example
# Set the maximum transmission rate of port GigabitEthernet 1/0/1 to 5.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] stp transmit-limit 5

Configuring Ports as Edge Ports

If a port directly connects to a user terminal rather than another device or a shared LAN segment, this
port is regarded as an edge port. When a network topology change occurs, an edge port will not cause
a temporary loop. Because a device does not know whether a port is directly connected to a terminal,
you need to manually configure the port to be an edge port. After that, this port can transition rapidly
from the blocked state to the forwarding state without delay.
Configuration procedure
Follow these steps to specify a port or a group of ports as edge port(s):
To do...
Enter system view
Enter
interface view
or port group
view
Configure the port(s) as edge
port(s)
Use the command...
system-view
Enter Ethernet

Remarks
—
Required
Use either command.
Configurations made in
interface view will take effect on
the current port only;
configurations made in port
group view will take effect on all
ports in the port group.
Required
All Ethernet ports are non-edge
ports by default.
